Sintaxis

'Declaración
Public Function FindLeafNodes As ContextNodeBaseCollection
'Uso
Dim instance As InkAnalyzerBase

Valor devuelto

Tipo: System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
Objeto ContextNodeBaseCollection que contiene todos los nodos hoja.

Ejemplos

En el ejemplo siguiente, se recorren en bucle todos los nodos hoja de un objeto InkAnalyzerBase, theInkAnalyzerBase, y se encuentra el que tiene el límite inferior más bajo.

' Find the leaf context node that has the lowest bottom bound.
' In the ink coordinates system a higher value is physically lower.
Dim lowest As Integer = Integer.MinValue
Dim lowestNode As System.Windows.Ink.AnalysisCore.ContextNodeBase = Nothing

Dim leafNode As System.Windows.Ink.AnalysisCore.ContextNodeBase
For Each leafNode In theInkAnalyzerBase.FindInkLeafNodes()
    ' Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
    ' array containing the left, top, right, and bottom bounds in order.
    If leafNode.Location.GetBounds()(3) > lowest Then
        lowestNode = leafNode
        lowest = leafNode.Location.GetBounds()(3)
    End If
Next leafNode

// Find the leaf context node that has the lowest bottom bound.
// In the ink coordinates system a higher value is physically lower.
int lowest = int.MinValue;
System.Windows.Ink.AnalysisCore.ContextNodeBase lowestNode = null;
foreach (System.Windows.Ink.AnalysisCore.ContextNodeBase leafNode
    in theInkAnalyzerBase.FindInkLeafNodes())
{
    // Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
    // array containing the left, top, right, and bottom bounds in order.
    if (leafNode.Location.GetBounds()[3] > lowest)
    {
        lowestNode = leafNode;
        lowest = leafNode.Location.GetBounds()[3];
    }
}
